beatmania IIDX 13 DistorteD adds more improvements to the series. Hi-Speed settings now go from 0.5 to 5.0 at .5 step intervals. The game also introduces 2P FLIP in which both players switch notepatterns (DP FLIP on Doubles in which the entire notepatterns switch sides). In addition, Hi-Speed modifications can now be changed during the song itself by holding the appropriate start button and pressing a black key to increase the speed, or a white key to decrease the speed.

The game features the first new logo for the series (the old logo dates back to 1998 and the release of the original beatmania), and many more new songs and crossovers from other Bemani games, such as "Samba de Janeiro" and "Concertino in Blue" from DDR Solo 2000 and Guitar Freaks/Drummania respectively. The theme for DistorteD is silver.

beatmania IIDX 13 DistorteD is a direct port of the arcade version, with one preview song from GOLD, as well as new songs, and some revivals.
